DENTAL ANfi MOUTH CLEANSING MEANS Filed March 11, 1940 Patented M.,'4, 1943 UNITED STATES PATENT OFFICE DENTAL AND MOUTH CLEANSING MEANS Bigelow Boyscn, Chicago, Ill. Application March 11, 1940, Serial No. 323,364

Claims.

This invention relates to improvements in dental and mouth cleaning devices.

Among the objects of the invention is that of providing an improved device for cleansing and refreshing the human teeth, gums and oral cavities that can be made to retail at so low a price, that the device may be discarded after a single use. The device will eliminate the oldfashioned handle of the toothbrush in current use and will be small enough to permit quantitles of them to be carried on.or about the person, thereby making it practical to clean the teeth and gums as often as desired.

A further object of the device is to supply a need that is felt by people who travel, in particular, who often find it necessary to pack the toothbrush generally in current use before the same has had time to dry, with the result that its efliciency is impaired and it becomes unsanitary. These and other deficiencies of the ordinary toothbrush have been overcome by the present invention which will be used but once and then discarded.

Because the device is eflicient and pleasant to use, and can be made of suitable materials at low cost, it will be made available to the public either without charge, as by carriers, hotels, clubs, etc. (which will purchase quantities for the convenience of and gratis distribution to their patrons), or at a price sumciently low (through channels such as drugstores, coinvending machines, restaurants, etc.) to justify their discard after a single use.

To attain these objects, I have provided a tube of sponge rubber, or other suitable material having a cavitated surface, open at one end and closed at the other, in the shape of a human index finger, which fits over and encases the index finger'from. its tip to a point between the first and second joints thereof. This tube is, in the process of manufacture, impregnated with a soluble dentifrice. Due to its elasticity and the means by which it is fitted onto the finger, as hereinafter specified, the tubular portion is adapted to human fingers .of varying sizes. I have further provided a ring upon which the tubular portion is rolled in the process of manufacture and by means of which the tube can be easily unrolled onto the finger when it is to be used.

"The accompanying drawing illustrates a specific embodiment of the invention which contains novel features and combinations by which the foregoing objects may be attained.

Figure 1 is a side view partly in section, of the tubular portion of the device as the same appears when fitted onto the finger.

Fig. 2 is a side or edge view of the device, part- 19 in section, as it appears when rolled onto a carrier or retaining ring which ring also makes it possible to easily apply the deviceto/the finger.

Fig. 3 is a front view of the same."

' Fig. 4 is a rear view of the same".

Fig. 5 is a perspective view of the carrier 0 retaining ring onto which the tubular portion (Fig. 1) is rolled for dispensing and handling Pu poses, and

Fig. 6 is a front view of the same.

In the form shown the invention comprises the combination of a tubular member, ofsponge rublber of suitable porosity and elasticity, or some other suitably porous and elastic material, which is open at one end and closed at the other end in substantially the shape of the end of a human finger, a quantity of dentifrice, suitably soluble, impregnating the outerside pores or cavities of said tubular portion and closed end thereof, and a hollow ring or annulus of a ma-', terial suitably firm and rigid, having an outer circumferential or peripheral surface that is concave in shape and lying between two radial flanges or rims (or the sides or margins of the ring) of unequal diameters, by meansof which the tubular portion, when rolled is held in such a position that it may be easilyunrolled and properly fitted onto the finger.

The ordinary sequence of certain. of the principal steps takenin the manufacturing of the device and, secondly, in its use,- will best illus-q trate the novel features and combinations thereof.

After the tubular portion (Fig. 1) is moulded, or otherwise shaped, the side wall thereof, beginning at the open end i is rolled outwardly along the axis of the tube to the closed end 2 thereof which is' thereby stretched to form a substantially fiat surface as shown in Figs. 2 and 4. The carrier ring or annulus 3 (Figs. 5 and 6) is fitted into the circular roll of the tubular member thereby created, so that the rear flange or rim 4, whichis of the greater diameter, becomes adjacent to the inside of the that stretched surface of the closed end 2- bordered The diameter of the smallby the circular roll. er outer flange 'or rim.5 of the ring is greater than the smallest inner diameter of the, circular roll, but slightly less than the center diameter thereof so as not to obstruct the application of pressure on said circular roll, as hereinafter specified, when the same is to be unrolled onto V of its manufacture or wrapping; Y

It will be understood that by the rolling down Although I prefer to have the ierence Q of the ring 3, between the rims l and 5.,-

the finger, the circular roll being outwardly stretched when the ring is fitted into it as afore- 'In such form, the device is ready to be fitted be. smaller than the average diameter of the average size adult human-finger upon which the same will generally be used. In this respect I prefer to use and adapt the device for use on the.

index finger,-although it canbe used or be made to be used on-any, of-the other fingers or'thumb.

onto the finger and used, having been impregnated by dipping, brushing, dusting or otherwise treated, with any suitable soluble dentifrice at some suitable and convenient step in the process of the side of thetubular portion, as aforesaid,

I have'found it most satisfactory to make the inner. diameter 'of the tube approximately A of an inchand the width of the walls thereof approximately %.'of an inch, letting the elasticity of the .walls (when the diameter of the tube is stretched as aforesaid) create acontracting pressure that will hold the tubular portion snugly on the-finger throughout the cleansing operation the side'thereof disappears temporarilyinto'the circular roll thereby created, the diameter of which roll is increased as the rolling progresses.

Byvirtue of this increase in diameter, each successivelayer of the 'tubular'material is increas-' ingly stretched as it becomes part of the roll. It will be seen therefore, that when the roll assumes the position shown in Figs. 2, 3 and 4, consider,

able contracting force has been created tending .to cause the roll tounroli itself baclt'into its orig which preferably has a-diameter greater than-the center diameter of the circular roll, but less than the outer diameter of said circular roll. When this tendency to unroll is so prevented, a second tendency of the contracting force becomes more active, viz a tendency of the roll to loosen and untension-its several convolutions.

- Thisglatter tendency is obstructed by the front:

'sition shown in Fig. 1.

when used. The tubular portion mayj'of course, be made in various lengths, and it will be noted that its length when in position for use on the finger, will vary somewhat depending upon the diameter of that portion of the finger so encased -I prefer to make the tubular portion 1 /2 inches in length, measuring same from the center of the inside wall of the elliptically rounded end to the open end thereof, while same is in the pot will be understood that the dimensions of the ring 3 will be dependentupon'the dimensions adopted for the tubular portion, having adue regard for the objects sought to be attained by Qther novel features-and combinations of the invention become apparent in the principal steps taken in thefuse of the device:-

After unwrapping the device, which'will then be in theshape shown inFigs'. 2, 3 and 4, in

whichposition, it will be understood, the ring 3 is partially concealed in the tube as so rolled, the fiat orrear side of the device, indicated at I in rim 5 of the ring 3, which rim has a diameter greater than theinside diameter of the circular" roll, but=less"than the'diameter of the-annular axis of-saidroll about which'the convolutions are formed. Without such retention, by the rim I, it wouldultimate in the circular roll turning itself inside out and assuming the shape shown l other, until, dueto the elasticity of the material ,comprisingthejtube; said tube is forced .back

in Fig,- 1, but in an inverse position. This second tendency is, however, less apparent thanthe first tendency above noted in view of the fact, among other -things,-.'that it is obstructed by the fricconcave'in shape to become adjacent at all points outer circuma pletely' encased infthe tubular portion of the :55 to the convex inner surface of the'rolled tube and Figs. 2 and 4, is pressed against the end of that finger of either, hand upon which the same is to be used, the flat surface yielding through the opening of the ring, bymeans of pressure brought vto.. bear by the fingers and thumbof the other hand, placed in-positions on thelfront of the roll thereby create a further obstacle (by frictional resistance) to the second tendency of. the con-- tracting force above noted,' such shape is not.

necessarily essential to the success of the invention, it being understood that the said outer'c'ir-E cur'n'ierence 6 of the ring Imay be given a num berx'ofother shapes'ithat wouldnot militate against the eiiectivenessoi' the said rims. Such ."other shapes may. be adoptedintheinterest ofeconomyof; manufacture withoutseriouslyim pairing the successful achievement of the job: .jects soughtto be attained by the ring. H -It will be further understood that the tubular Just outside of the'circumference of the front rim 5 ofther'ing 3 and roughly equidistant from each over' the rear 'i'i-m lof'the ring 3 and off of the to bear. Such continued pressure .will cause the f roll to completelynnrollxitself onto the finger causing a portion'of the said finger to be comdevice.

As previouslystated, the ring 3 was held in the :circular roll ofthe tubular. member by thev elastic, contraction of said roll, and when that I "roll is forced back'over the rear rim and onto the finger as aforesaid. the ring. is released, falls away of its own weight and may be discarded.

After the circular roll is completely unrolled onto --the:finger the finger so partially enveloped by the tubular p rtion may be dippedin. water whereupon'it is ready for use in cleansing and refreshing theteeth, gums and oral cavities, hav- 'ing already been impregnated with a tifrice-as before stated. I

I The importance of the ring portion 3 of the device becomes apparentwhen it is remembered that theins'idediameter ofthe tubular portion" 01 the unrolled device is less thanthe diameter of the portion of the flnBer that the tube encases. Under such-circumstances it would be-trouble-' some tofit the tubular portion onto'the linger soluble den-' I were it not for the fact that the ring 3, upon which the tubular portion is rolled in the process of manufacture, holds the rolled tube in such a position that its substantially flattened end surface 'I may be pressed against the finger and the tube unrolled onto the finger to encase a portion of it as hereinbefore specified.

I do not mean to limit myself to the shape of either part of the device as illustrated in the drawing. It will be understood that the tubular portion can be made to fit the finger in varying shapes and have various surfaces, 1. e., such as corrugations, etc., while yet applying the same principles as disclosed. By such variation the tubular portion could be readily made to have only its tip and under surface, as used on the finger, provided with the cleansing element retaining cavities, while the top portion thereof might be made of a non-porous material, or a less porous material, and have a wall considerably less in thickness. Such a non-porous or less porous material could be made to wholly encase the portion of the finger covered, thereby serving as a base or lining for the porous or eavitated cleansing element which would be permanently attached to the underside and tip of said linin or base, as used on the finger. Such variations in shape can also be accomplished by lessening the thickness of the wall of the top portion only of the tubular portion of the device as used on the finger. Such variations in the tubular portion would, of course, call for corresponding variations in the shape and dimensions of the rin element of the device.

Although but one specific embodiment of this invention is herein shown and described, it will be understood that numerous details of the construction shown may be altered or omitted without departing from the spirit of this invention as defined by the following claims.

adapted to receive the rolled tubular member on its outer periphery and having axially spaced radial end flanges of difierent radial widths.
